Nginx

Nginx was written with an explicit goal of outperforming the Apache web server.Out of the box, serving static files, Nginx uses dramatically less memory than Apache, and can handle roughly four times more requests per second.However, this performance boost comes at a cost of decreased flexibility, such as the ability to override systemwide access settings on a per-file basis (Apache accomplishes this with an .htaccess file, while Nginx has no such feature built in).
